Leadership has to reside in the private sector, and the key thing the private sector has to ask for from policy makers and politicians is a change in the way we measure the economy. This is the belief of Pavan Sukdhev, visiting fellow at Yale University and author of the book “Corporation 2020: Transforming Business for Tomorrow’s World” (Island Press, 2012). In this video, Sukdhev explains just what is needed to create the ‘green economy’, which will provide sustainable profits for companies without damaging natural, societal or human collateral. He makes a plea for a wholly new measurement framework that assesses whether a firm’s ‘externalities,’ e.g. its impact on people and the planet, are positive or negative.
